Next problem.

I compared PCI bus setting for working Dell 1525 and non-working Dell D420

PCI addr 	1525		420
(00)=08221180   	08221180   	DeviceID the same
(08)=08050122   	08050118	kIOPCIConfigRevisionID
(0c)=00804010		00804000	kIOPCIConfigCacheLineSize
(3c)=00000212		00000312	kIOPCIConfigInterruptPin
(b0)=00020004		00020000	
(c0)=00003000   	00000000	
(f8)=002100c0		022000c3   	

 

The problem that I can't find information about this PCI addresses specific for Ricoh SDController.

Can anybody find a datasheet for it?

Do you want to have a look at my card reader in inspiron d640m????

 

Problem so far work for some sd card but prevents me from waking from sleep.....

 

 

Let me know If you need any info from my card reader....

 

Try this version. It works on Dell Inspiron 1525 with correct sleep/wake.

VoodooSDHC.kext.zip

 

 

This is debug version with many messages in kernel.log.

Report, please, with this messages.

 

It seems Inspiron has more recent SDController rev2.2 that works with this driver while D420 has rev1.8 that is quirky and some workaround in driver needed. I still not found the trick in any Linux/FreeBSD/Nintendo sources.

Is there anybody can confirm that the SDCardReader works in Linux? I doubt.

Slice does the sdhc kext not load at all on your d420???

 

I just tried on my d430 kext loads at start up if i put a card in it says card found but then it says many error codes then i have to restart laptop....

 

 

This is my device and kext with system info app

device.tiff

kexts.tiff

 

I asked to provide kernel.log information. And please attach pictures as png but not tiff.

 

Yes, on D420 almost the same behavior. At Inspiron it just works, card inserted automatically mounted and I can read and write with a speed about 10Mb/s.
